Abstract

Common bean (Phaseolus vulgaris) have great economic and social importance worldwide and is the widely distributed crop in the world and the main food legume in Americas, especially in Brazil, Mexico and the USA (Sikora et al., 2005). Brazil is the second largest producer and is responsible to 15% from the world production with an annual mean consumption of 3.25 million ton (MAPA, 2013). However, the productivity is compromised due to pests, diseases and weeds that occur in the crop, with emphasis to phytonematodes.

In bean growing areas, yield losses caused by nematodes from genera Meloidogyne, especially M. incognita and M. javanica, have been frequently reported in Brazil (Inomoto, 2011) and can reach 50 to 90 % (Simão et al., 2005). Meloidogyne incognita, M. javanica and M. arenaria are the most common root-knot species associated with P. vulgaris causing extensive losses in the Americas, Africa and Asia (Di Vito et al., 2005, Sikora et al., 2005; Sikora & Greco, 1990). Besides these species, M. paranaensis and M. enterolobii can also occur in the crop (Machado, 2011). Recently, novel root-knot species were detected in bean growing areas in Brazil, M. inornata (Machado et al., 2013) and M. luci (Machado et al., 2016).
